HEADLIGHT FOR LOCOMOTIVES.

Application tiled August 10, 1314i Serial No'. 856,124.

To all whom t may concern.'

Be it known that we, GEORGE L. CON'NER and GEORGE BYRON, citizens of the United4 States, residing at Williams, in the county of Coconino and State of Arizona, have invented certain new and useful Improvements in Headlights for Locomotives, of which the following is a specification, reference being had to the accompanyingy drawings.

This invention relates to certain improvements in headlights for locomotives and the object of the invention is to provide a device of this general character having novel and improved means whereby the reflector may be automatically adjusted whereby the rays of light will accurately follow the curves of the track. i

The invention consists in the details of construction and in the combination and arrangement of the severalparts whereby certain important advantages are attained and the device is rendered simpler, less expen sive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully' set forth.

The novel features of the invention will be carefuly defined in the appended claims.

In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a vertical section taken through a headlight constructed in accordance with our invention; Fig. 2 is a sectional view taken on the line 2-2 of Fig. l1; Fig. 3 is a view in rear elevation ol" the device as herein shown in Fig. 1; with certain of the parts omitted; and Fig. .4 is a sectional view on the line 4-1 of Fig. 1.

As. disclosed in. the accompanying drawings, 1 denotes a lamp casing or housing adapted to be properly mounted upon a locomotive, the forward face of such casing or housing 1 being open and adapted to be inclosed by the transparent cover 2, herein :hown as semi-circular in cross section for purposes which will be obvious., This transparent closure 2-isadapted to be detachably maintained 1noperative 'position and for this purpose the. `free edge portions of the lsuchcover-2, said cover being capable of resides of the housing or casing 1 are provided with the guides or tracks 3-3 adapted toaccommodatethe marginal portions of specification of Letters Patent.

J moval upon the release of the top 1a of the casing or housing l.

Supported by the top and bottom of the housing or casing l and mounted for movei ment onnxzertical axis is a lamp support 4 herein shown as of an arc type. The details of the lamp form no particular part of the resent invention other than that the relec ing member or plate 5 positioned to the rear of the carbon 6 is adapted to move with the axial adjustment of the lamp and for that purpose we provide Such reiiecting member or plate 5 atithe substantial centers or' 1ts upper and lower margins with the inwardly directed arms 7-7 having produced in their extremities the openings 8 angular in cross section and through which are adapted to be positioned the carbon holders' 9 of a form in cross section similar to the openings 8 whereby it will be seen that upon rotative movement of the lamp the reflector vided with an upstanding lug 14: adapted to be embraced by the annular member 15 produced on the inner end of the elongated member 16 mounted for endwise movement through the upper end portion of the pendulum 17 pivotally supported intermediat; its length, as at 19, by the rear Wall of the casing or housing 1.

The pendulum 17 is provided intermediate its length with a plurality ofopenings 20 through which the pivot 19 is adapted to project whereby it will be observed that rotative travel of the lamp or more particularly the reiiector .thereof may be ei'ectually regulated or controlled. The lower end portion of the pendulum 17 passes beneath a strap or guide member 22 which serves to' prevent movement of such lever toward or from the housing 1, as would tend to injure the same which movement would be liable to occur either at the starting or stopping orJ the locomotive 'to which our improved device may be applied. Theportion of the'pendulum 17 below the strap 22 is providedwith the weight 23 capable of adjustment `lengthwise thereof and being ther hold the lamp against undue vibration or movement on .its pivot, we secure to the rock arm 10 the laterally directed resilient Wings 25 herein shown as integrally connectedjand provided with an nturn portion 26 through which suitable securing means are adapted to pass to hold the same to the arm'. These wings are adapted to frictionally engage the adjacent face of the rear I wall of the housing or casing 1. In order to maintain the wings 25 in yieldable frictional engagement with the rear wall of the casing We interpose between the lever 17 and nut 27 afcoiled spring 28 bearing upon said nut and the lever and disposed about the endwise movable member 16. The spring 28 yieldably permits slight relative movement of the rock arm and pendulum also preventing lost motion. It is also to be observed that the upper extremity of the lever lTis provided with a plurality of openings 29 through which the endwise movabley member 16 is adapted to project andthereby providing a means to compensate for any adjustment of the pivot of such member.

From the foregoing description of our improvements, itis thought to be. obvious that-a headlight constructed in accordance with our invention is of an extremely si1nple and comparatively inexpensive nature and is particularly well adapted forv use by reason of the convenience and facility with which it may be assembled and of the manifest advantages afforded thereby ir having therays of the light. so directed as to follow the curve and it will also be obvious that our invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason we do not wish to be understood as limiting ourselves` to having yieldable connection with said rockv arm to prevent rattling of the parts and to' tend to maintain said frictional means in operation when the lamp support is moved.

The combination with a casing having a lamp support revolubly mounted therein and having a rock arm Yextending rearwardly thereof, of a pendulum, means yieldably connecting the rock arm and the pendulum, means carried by the rock arm for yieldable frictional engagement with 'the rear wall of the casing, said yieldable Connecting means coacting with 'said friction means to prevent rattling and lost motion of the parts when in' use.

` The combination with a casing having a lamp support rcvolubly mounted therein provided with a rock arm extending rearwardly thereof through an opening in said casing, a plurality of lflexible wings carried by the rock arin to engage the rear wall of the casing adjacent said opening, a pendulum, and a. yiolda-ble connection between the rock arm and the pendulum coacting with the wings to prevent undue motion and vibration, and assisting in maintaining said wings in snug engagement with-thc rear wall of the casing.

ln testimony whereof We hereunto alix our signatures in the presence of two wit* iie'sses. y
